Abstract: In the current bridge engineering, BIM technology has high application value. The BIM software can be used to quickly detect the established BIM model to find the deficiencies and collision problems in the bridge design plan, and the amount of various materials in the actual bridge construction can be quickly and accurately calculated, and then carry out the bridge construction management work. In order to ensure the efficient, safe and stable construction of the Peisen Liujiang Bridge, BIM technologies such as pile base layer analysis, steel bar collision detection, construction progress simulation, and engineering quantity statistics have effectively guided the on-site construction and provided better technical support for improving the quality and efficiency of the project.
